I have plotted a triangular plot, three dimensions of which represent three herbal strategies. One dimension represents the strategy of C (competitive plant), the second dimension “S” (stress tolerant plants) and the third dimension”R” (ruderal plants), as you can see in the image bellow the points on it represent the plant species. Now I am trying to write name of the plant species outside the triangle and connect with the arrow to the corresponding point. How do I do this work? Many thanks in advance as it would help me a lot in my work.
